Phase Envelope Software

Hi All,

My company is looking for a software that could help us determine the phase envelopes of mixtures and in turn determine the dewpoint and bubblepoints of the mixture. Simulations software like CHEMCAD does have the function to developed the phase envelopes, just that we do not really use other portion of the the simulation like Distillation column sizing, pipe sizing etc.

I have search online and so far it seems that VLEFlash from flowphase met the requirement. But to date, i did not see other software that is close to this VLEFlash.

Anyone got experience of generating phase envelopes diagrams (for Dew point and Bubble point) from other softwares that dun mind sharing with me?

thanks a lot
